• Watch the Transducer installation video found on the Fish Hawk Website. 
• We install marine grade plastic transducer mounting boards on the back of 

our boats because they allow us to change the position of transducers without 
drilling new holes in the transom.

Sonar Interference

Sonar interference is caused when similar sonar frequencies are used in close 

proximity to one another. The Fish Hawk uses a 70 kHz frequency while most fish 
finders operate around 200 KHz, meaning the Fish Hawk will not interfere with 
most fish finders. Some dual frequency finders use a 50 or 83 kHz frequency that can 
interfere with the Fish Hawk at high gain settings if the transducers are mounted too 
close together on the transom. You can opt not to use the 50 or 83 kHz frequency in 
your fish finder’s settings if it causes a problem, or relocate the Transducer on the 
transom. Lowering the gain will help the Fish Hawk minimize interference but may 
reduce the usable depth range.

Installing the Display

Place the display in a visible location on the helm. An optional foul weather 

cover is available for purchase on-line if you plan on leaving the 
display in an exposed location.

You can flush mount the display into your boat’s console by 

cutting a 3 1 ⁄2” wide x 6 1 ⁄8” tall hole in the dash and using a 
silicone sealant to secure the display in place. 

The display requires that two connections be made; 

the power cord and the Transducer. Additional 
wire can added to the power cable if you follow 
the proper polarity (+/-.) The display is protected 
by an in-line 1 amp fuse. As with most radio 
or sonar devices, we recommend wiring the 
display directly to a 12-volt battery. Connecting 
to a fuse block can result in unwanted electrical 
noise that can interfere with the Fish Hawk.

Pull rubber fuse  

housing apart to access fuse.

Use the four 

holes at the 

bottom of 

the base to 

secure it in 

place. There 

are two holes on 

each side of base.
